Excitonic magnetism at the intersection of spin-orbit coupling and crystal-field splitting
Excitonic magnetism fr6122 involving superpositions of singlet and triplet states is expected to arise for two holes in strongly correlated and spin-orbit-coupled t_{2g} orbitals.However, uncontested material examples for its realization are rare.We apply the variational cluster approach to the square lattice to investigate excitonic antiferromagne
